Translate the sentence into an inequality. Four times the sum of a number and 23 is at least 21.
Use the variable y for the unknown number.

Help this is a simple quick question that I don’t understand

do you have the measurements?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
